Research Shows Possibilities For Quasicrystals
2013-03-20 08:56:27

Syracuse University Ever since their discovery in 1984, the burgeoning area of research looking at quasiperiodic structures has revealed astonishing opportunities in a number of areas of fundamental and applied research, including applications in lasing and sensing. Quasiperiodic structures, or quasicrystals, because of their unique ordering of atoms and a lack of periodicity, possess remarkable crystallographic, physical and optical properties not present in regular crystals. In the...

Forget solid, liquid, and gas: there are in fact more than 500 phases of matter. In a major paper in today's issue of Science, Perimeter Faculty member Xiao-Gang Wen reveals a modern reclassification of all of them. Condensed matter physics — the branch of physics responsible for discovering and describing most of these phases — has traditionally classified phases by the way their fundamental building blocks — usually atoms — are arranged. The key is something...

Researchers Find Limit On CPT Violation From Gamma-Ray Bursts
2012-12-07 15:12:11

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in the journal Physical Review Letters that they have found evidence of a strict limit on CPT violation from polarization of gamma-ray bursts. Photons produced by gamma-ray bursts travel billions of light years to reach the Earth. This makes them excellent probes of space-time structures on extremely small scales. Some quantum gravity theories predict that structures of space-time at extremely short...

SLAC National Accelerator Laboratory Time's quantum arrow has a preferred direction, new analysis shows Time marches relentlessly forward for you and me; watch a movie in reverse, and you´ll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse — a concept known as time reversal...

Physicists Make Perpetual Clock With 4 Dimensional Crystals

Alan McStravick for redOrbit.com - Your Universe Online Theoretical Physics made a huge leap from concept to reality yesterday thanks to collaboration between an international team of scientists and researchers with the U.S. Department of Energy´s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab). The team has proposed the experimental design of a space-time crystal that is based on an electric-field ion trap and the Coulomb repulsion of particles that carry...

Asymmetric Warfare Between Earwigs Probed By Researchers
2012-08-16 07:07:24

Symmetrical looks are highly prized in the animal kingdom, but according to a new report by San Francisco State University biologists on an insect called the maritime earwig, asymmetry might come with its own perks. Animals–including humans–seem to use symmetry as a shortcut for evaluating potential mates. Symmetrical features usually indicate normal development, while asymmetry could point to an underlying developmental defect that would render a mate less fit. "The...

In Search Of Natural Quasicrystals
2012-08-10 04:32:11

April Flowers for redOrbit.com - Your Universe Online An expedition to far eastern Russia, a 15,000 year old meteorite, secret diaries, smugglers, gold prospectors and bears; sounds like the plot to an Indiana Jones movie, right? This is the story of two researchers looking for the origin of naturally occurring quasicrystals. Who knew science could be so exciting? Writing in Reports on Progress in Physics, Paul J. Steinhardt and Luca Bindi reveal that new, naturally occurring...
